If you don't recognize the name, you'll almost certainly know his most famous role. David Ogden Stiers became a star through playing Major Charles Emerson Winchester III on the hit show M*A*S*H. You may have also heard his voice quite a few times without realizing it was him; his voice acting credits include the Disney movie "Lilo & Stitch", and "Beauty and the Beast". While the big roles paid the bills for him, he was always more at home on the stages of Broadway.
Stiers left it late in life to announce himself to the world, only coming out as gay in 2009. He'd been battling against bladder cancer for a while at the time of his death, but it wasn't the cancer itself which killed him. He sadly suffered a number of complications related to the cancer and its treatment and passed away because of them. He was 75.
